Choose the conjunction of time that tells how long to wait: stop waiting when the bus arrives. Drop it into the gap and read the instruction.
The intended instruction is "Wait in the shelter until the bus arrives." Until gives the end point of the wait. Other conjunctions may form grammatical sentences, but they change the intended relationship. Here the question asks for the time link, not a different condition, contrast or purpose.
What to say if they get stuck
- Ignore the chips for a moment. Ask what the second half is DOING to the first: giving a reason, setting a condition, marking a time, or turning it around.
- The instruction asks for a time link. Other conjunctions can make grammatical sentences, but they express a different relationship.
- Read it back with each chip in place. "Wait in the shelter until the bus arrives" says a point in time, which is what this pair means.
